Functional Description
1. IPLOOK S-CSCF network element support the following main functions:
 To handle registration requests by acting as a registrar as defined in [RFC3261].
 To authenticate users by means of the IMS Authentication and Key Agreement (AKA) schema.
 To download user information and service profile from the HSS during registration or when
handling a request to an unregistered user.
 To route mobile-terminating traffic to the P-CSCF and to route mobile originated traffic to the I-
CSCF, the Breakout Gateway Control Function (BGCF) or the application server (AS).
 S-CSCF Enhanced iFC Handling
 To interact with RCS
 Sending of SIP OPTIONS for remote peer availability
 To translate an E.I64 number to a SIP universal resource identifier (URI) using a domain name
system (DNS) translation mechanism
 To send accounting-related information to the CCF for offline charging purposes and to the Online
Charging System
2. IPLOOK BGCF network element support the following main functions:
 With integrated BGCF, processes requests for routing from an S-CSCF when the S-CSCF has
determined that the session cannot be routed using DNS or ENUM/DNS.
 Processes the interworking with the PSTN/CS Domain, when the BGCF has determined that a
breakout should occur in the same IMS network to send SIP message from BGCF to MGCF.
3. IPLOOK I-CSCF network element support the following main functions:
 To allow detection of an INVITE request addressed to a special address, triggering the Cx LIR
query to use the IMPU from the P-Asserted-Identity header.
 To modify the Request-URI type, e.g. from TEL URI or SIP URI to SIP URI with user=phone.
 First Point of Entry(From P-CSCF in home network or From P-CSCF in visited network)
 S-CSCF Assignment by selection based on assignment in HSS
4. IPLOOK P-CSCF/SBC network element support the following main functions:
 3GPP R10 compliant Proxy-CSCF (P-CSCF) function
 Support for Gm, Mw, Rx, Rf/Ro interfaces

Product Strategy
The IMS product offers Virtualized platform deployment, using x86 standard server with linux 64-bit
platform, as the following hardware:
KTVIMS Server
The IMS network element can be directly deployed on the x86 server to reduce the CAPEX.
Based on capacity, vIMS can be deployment in two ways:
1. All in one platform, one x86 standard server deploy all the IMS network elements including
CSCFs/BGCF/AS;
All in one Deployment
2. Shelf platform, the IMS network elements are separated into different server, and multiple same
elements to support big capacity.
